Abstract

The relationship of the structure with the strength, deformation, thermophysical and tribological characteristics of linear block-copolyurethanes based on oligoeters of regular structure oligooxy tetra-methylene glycol is described by mathematical model. Quality parameters are used to estimate the relationship between the structure and properties of the studied materials. The quality parameters allowed to find optimal composition of initial components.
